Number (mult/div)

UK Primary (3-6)

Divide a 2 digit number by a 1 digit number using area or array model

Let's use an area model to find the answer to $30\div2$30÷2.

a

We set up the area model using a rectangle like this.

$2$2 | |

Total area: $30$30 |

Now if we don't know straight away what $30\div2$30÷2 is, we start with something we do know, like groups of $10$10.

Fill in the area used so far if we take out $10$10 groups of $2$2.

$10$10 | ||

$2$2 | $\editable{}$ | |

Total area: $30$30 |

b

How much area is remaining?

$10$10 | ||

$2$2 | $20$20 | $\editable{}$ |

Total area: $30$30 |

c

What is the width of the second rectangle?

$10$10 | $\editable{}$ | |

$2$2 | $20$20 | $10$10 |

Total area: $30$30 |

d

Using the area model above, what is $30\div2$30÷2?
